Play with her tits

You pull her skimpy top off over her head, and she lifts her arms up to let you strip it off of her body. Her big soft breasts flop out as you pull the shirt over her head, hanging down heavily on her torso just above her soft belly. You pick them up and cup them in your hands, feeling their soft weight and the warmth of her skin. They're a little more than a full handful each, and you give them a good squeeze to confirm that you can't quite get your fingers all the way around. "Damn, these big jugs of yours are amazing," you muse out loud, and flick your thumbs over her nipples, which are standing up stiffly.

Melissa giggles again, although you're not sure whether it's because of your compliment or the breast stimulation. "Thank you!" she says, in a sincerely appreciative tone. "Yeah, I'm lucky to be so well-endowed. Guys really like my chest, I get plenty of use whenever I'm outside—someone's always groping me or asking me to shake my tits. Do you want to see? I've been practicing."

That's not a question you would have ever expected to get before today, but there's only one possible answer. "Sure, I'd love to," you say with a nod. You let go of her breasts, albeit slightly reluctantly, so she can move. She puts her hands on her hips and starts rocking her shoulders back and forth alternately, twisting her upper torso so that her tits sway rhythmically side-to-side. It's a steady, measured motion that bounces her heavy breasts at just the right speed, keeping them moving enticingly without any comical flopping about. It also looks like a pace she could maintain for a long time before getting tired.

It looks like her practice paid off, you think to yourself after a few minutes of watching her boobs jiggle around. Something she said is tickling the back of your mind, though—"You said you feel lucky to have tits like yours," you say. "Do you like being a big-breasted cumdump?"

"I do!" she says, still shaking her tits back and forth. "I really do. A lot of guys, and even smaller-breasted women, sometimes, don't know how fulfilling it is. I make people happy every single day." She says this with an intensity that seems oddly out of place with the sight of her jiggling breasts. "Sometimes I'll run across some guy who's had a rough day—you know that look people get, that slump, like they're carrying the whole world on their back. But then he sees me, and his face just lights up, because whatever the problem was, he gets to forget about it for a while. It's not crushing him down as long as he's got his cock in my mouth or up my ass, and when he's done using me as his jizzrag he walks away with a smile on his face. Yeah, you bet I like it."

You blink, caught off-guard by the eloquence of her reply. "It sounds like you've put some thought into this before," you say, unable to wholly keep the surprise out of your voice. Then again, it shouldn't be all that surprising—she's an educated, intelligent woman in a society where free use is a normal, recognized part of daily life. Of course she's thought about it before, and about how it fits into her conception of herself and her place in the world.

Melissa looks slightly abashed. "Sorry, I didn't mean to monologue at you. You just touched on something I feel strongly about, that's all."

"Oh, no, that's fine," you reassure her. "It's really interesting, actually. I've never talked about this in depth with any other girls like you before." Which is true enough, even if only because it wouldn't have been possible for you to do so until today. "You're going to love being my neighbor, then. I can already predict you'll be making me happy on a daily basis." You cup her swaying boobs with your hands, and she stops shaking her chest so that you can handle them. You give each of them a light slap from below, first her left breast and then her right, just enough to make them bounce around on her chest a bit more. You give her nipples a final tug, pinching them gently between thumb and forefinger, before turning your attention to the rest of her body. You've got a lot of girl left to try out, and you'll have plenty of time to play with her big breasts later. For now, you're going to...
